WATCH | The most bizarre Red Card in rugby history!

Millions of years of evolution have taught our bodies that pain is bad and should be avoided as much as possible. But for some people, pain is just a minor inconvenience on their road to glory.

So while most of us can’t so much as stub our toe without collapsing into the foetal position, here are some England internationals who prove that sometimes what doesn't kill us inexplicably makes us stronger.

The loosehead-prop picked up the leg fracture during the first half of Quins’ 24-17 defeat at Worcester in 2017 but played on and completed the 80 minutes. Hard man.

“In the first half against Worcester away,” said Marler. “The trouble was I did it in the first half and just thought it was a calf knock and pulled my calf as well so there was a bit of confusion there. I thought I could keep running on it because running is not really my forte anyway so I could get away with hobbling a bit.

“I got to the end of the game and said ‘strap it up it’s just a tight calf or whatever’, and then because of the frozen pitches and the weather, we didn’t really get a chance to run it again until the following week’s warm-up which I said to them ‘I’ll be alright, I’ll just run it off’ but I couldn’t run it off because my leg was broken.”

The England fly-half suffered a stress fracture to facet joint in his neck after series of heavy collisions during the 2003 Rugby World Cup. The injury was only discovered when Wilkinson underwent a CT scan upon his return to Newcastle Falcons.

A statement from the club said: "Following a CT scan Newcastle Falcons confirm that Jonny Wilkinson has a slight fracture of a facet and believe this may have happened several weeks ago."

Bony scar tissue touching nerve sent shooting pains through right shoulder and arm over a long period of time.

He finally had surgery in 2004 after playing through the pain longer than he should have.

Tuilagi revealed this story in the lead up to the 2019 Rugby World Cup: “I used to put padding around my pubis and then strapped around it.

“It’s not nice — I wouldn’t wish it on anyone. I played five games with it being really painful. It was stupid.

“I pulled my adductor in my thigh but had no idea what an adductor felt like if you pulled it.

“I did it on the Thursday, played on the Saturday and strapped it up.

“I played five games with it — and it went higher and higher into my groin.

“At one stage I started strapping my pubis. The physio was like ‘What are you doing?’ I said ‘Er, nothing’.

“In the fifth game I got the ball in the first 20 minutes, went to accelerate and, bang, there was a loud pop and I couldn’t walk.

“I had pretty much dislocated my pubic bone.

“So I know how Ruaridh’s feeling. I said ‘keep your head, keep going and think positive’.

“At that moment there’s nothing anyone can say to make you feel better.

“But he will be back in a short period of time.”

The Bath Rugby winger, still just 22, has not played in the Blue, Black and White since last season having suffered a serious knee injury while away with England at the Rugby World Cup.

To make matters worse the winger continued to train on the damaged knee throughout the course of the tournament in Japan and played with it heavily strapped while scoring two tries against the USA in his only appearance of the tournament.

The result of which was Cokanasiga not only damaged his knee but caused secondary problems to his lower body and back which was overcompensating for the weakened area of his body as the 6ft 3in 18 and half stone back did more than 20km a week of running on his injured limped.  Hopefully, we see him back soon.
